Why do I feel very fatigue?

im feeling fatigue with no apetite and feel as if im going to pass out and die. what causes these symptoms to trigger?? example?? im not eating healthy and I drink alcohol everyday and sometimes it triggers anxiety in me?? but now I just feel very weak, dizzy, shaky, and blurry vision.

There are a wide range of conditions that could cause those symptoms, every one of which are saying get to a doctor as soon as possible!

Yes, see a doctor... and in the meantime, you may want to modify your diet and alcohol consumption. If your body's fighting off something, give it a helping hand.
